假设我有一些像这样的Flutter代码:
// ...
body: new Center(
child: new Text(
'Hello, I am some text',
),
),
// ...
如何让屏幕上的文字响应水龙头? (例如,当我点击文本时,只需打印到日志。)
谢谢!

如此answer所示,您可以使用InkWell或手势检测器。
例如
new InkWell(
child: new Text("Hello"),
onTap: () {print("value of your text");},
)
或者
var textValue = "Flutter"
new InkWell(
child: new Text(textValue),
onTap: () {print(textValue);},
)
编辑:正如Collin Jackson建议的那样,你也可以使用FlatButton
new FlatButton(
onPressed: () {print("Hello world")},
child: new Text("Hello world"),
);
如果您不需要或不需要材料(FlatButton,InkWell等),您可以使用GestureDetector:
new GestureDetector(
onTap: () { print("I was tapped!") },
child: new Text("Hello world"),
)

您可以使用RTF文本作为可点击文本:-
相应地在“文本跨度”中划分文本,并在要使其可点击的文本中使用“点击手势”。
TapGestureRecognizer _termsConditionRecognizer;
TapGestureRecognizer _privacyPolicyRecognizer;
@override
void dispose() {
_privacyPolicy.dispose();
_termsCondition.dispose();
super.dispose();
}
@override
void initState() {
super.initState();
_termsConditionRecognizer = TapGestureRecognizer()
..onTap = () {
print("Terms and condition tapped");
};
_privacyPolicyRecognizer = TapGestureRecognizer()
..onTap = () {
print("Provacy Policy tapped");
};
}
@override
Widget build(BuildContext context) {
return Container(
child: Center(
child: RichText(
text: TextSpan(
text: 'By signing up you agree to the ',
children: [
TextSpan(
text: 'Terms And Condition',
recognizer: _termsConditionRecognizer,
),
TextSpan(
text: ' and ',
),
TextSpan(
text: 'Privacy Policy',
recognizer: _privacyPolicyRecognizer,
),
],
),
),
),
);
}

您还可以使文本以URL的形式显示,如下所示:
new FlatButton(
onPressed: () {print("You've tapped me!")},
child: Text(
"Tap me!",
style: TextStyle(color: Colors.blue, decoration: TextDecoration.underline)),
);

另一种方法
创建返回可点击小部件的函数:
Widget tapableText(String text, Function onTap) {
return GestureDetector(
onTap: onTap,
child: Text(text),
);
}
用法示例:
...
child: tapableText('Hello', () { print('I have been tapped :)'); }),
...
